Approximately 100 people are to lose their jobs at the Football Association in a restructuring being carried out under the chairman, Greg Dyke, and new chief executive, Martin Glenn. The job losses are understood to be in all areas at the FA except the technical football department, and at all levels of seniority.

Staff have been expecting a large number of job losses since Dyke appointed consultants last year and more recently promised more money for investment in 3G football facilities, and they were told about the restructuring in a series of departmental meetings on Thursday afternoon. From Monday the FA will engage in a formal, 45-day consultation period, at the end of which 100 people are expected to accept severance packages or be made compulsorily redundant.

The cull is said to amount to a financial saving of more than £5m, part of the FA’s plan to cut £30m from its spending by the end of the year. The rest of the £30m, Glenn said, will be come from refinancing the loan on Wembley, the departures of several former senior executives, including the general secretary Alex Horne earlier this year, and more general cuts.

The savings are being made principally to release money for investment into grass-roots facilities around the country, following Dyke’s commission established in 2013 to address the declining number of English players fielded by Premier League clubs. His commission’s proposal for a B league of Premier League junior teams was roundly rejected within football, and was followed by a promise to build 3G pitches in 30 cities, starting in Sheffield.

Glenn, who has overseen similar restructuring programmes understood to involve job cuts in previous corporate roles including the snack conglomerate United Biscuits, joined the FA in March. In July three senior executives – Jonathan Hall, Roger Maslin and Alistair Maclean – left, which the FA stated was “part of its programme to re-prioritise significant investment towards the grassroots and England teams.” Glenn announced last week the FA will invest £260m over four years in the “national game” below professional ranks; an increase of £15m a year on current spending, which will include £10m for the 3G pitch programme.

Announcing the 45-day consultation, Glenn said the FA is adopting “the practices of leading edge organisations” and “putting football back at the centre of the FA. In creating this extra funding pool we can start to build more 3G pitches and create bursaries for coaches, with the ultimate ambition of resourcing our elite England teams to give them the best chance of success at tournaments.”

Referring to “the down side” of laying off staff, Glenn said: “It’s about making hard choices about what activities we want to prioritise and what we pull back from.”

The redundancies come at a time of financial boom in English football, with the Premier League’s 20 clubs expecting to make a record £8bn from its 2016-19 TV deals. The FA itself increased its income by £33m in 2013-14, the year of its most recent published accounts, to £332m, with TV rights accounting for £111m.

At FA board level there has been a concern that the organisation is over-staffed and a review was necessary – 728 staff “promoting association football” are noted in the 2013-14 accounts.

However, some within the FA will question whether so many people have to lose their jobs, to save a comparatively modest sum for investment in 3G pitches. Last year £47m of the FA’s money went to the wealthy professional game, including £28m principally in match fees and prize money to Premier League clubs competing in the FA Cup.
