2BthatUnnoticed - "How can the wages bill be GBP 350,000 per month "
From original thread:
We have around 100 employees earning approx 35k a year. Many of them are highly skilled in sought after roles.
"Yes (working at Mumsnet) and Gransnet. And they are running the site - tech, product, community management. We have a team running the jobsite. A team running gransnet, a video team, a small data and analytics team, an offers and deals team, a team that runs insight and product tests, a sales team, a finance/admin team, a team that produces mumsnet editorial content, a press team, hr, seo and email management etc..."

I don't think it was clarified anywhere in the thread how many people and staff hours are assigned to moderating the Talk Boards
Although Justine said "earnings" it was later suggested that this was the total employee costs / wages bill so it included "on costs" (national insurance, pension contributions, etc.) - so less approx 20% to give average pay = £28K
However, I don't know if this was confirmed by Mumsnet - that is one hell of a thread to trawl through and I think there were others from MNHQ responding as well as Justine.
Whatever, 100 seems to be a "head count" rather than "whole time equivalent" so some staff might well be part time. Though I might wrong 
No idea what full-time hours are but the number of "productive" hours actually available will keep dropping as you factor in: training and development, annual leave, Public Holidays, Parental Leave (if not covered by temporary appointments), sick leave, etc.
Apologies if I am teaching my granny to suck eggs. I used to manage a small team that provided a range of discrete services. Service-users always assumed that all staff worked full-time, were dedicated to delivering whichever service they used and worked 7 days a week, 52 weeks a year.
Once you knock off all the time that is not "productive", ie. not spent actually delivering a service, you could be down to as little as 30 weeks a year depending on leave, training time, etc.
100 staff might sound a lot but the productive time equivalent might be 60 - 80 staff - and we don't even know whether they all work full-time.
No idea what the Terms & Conditions are but there are some basic clues here, eg "London Living Wage employer."

TBH I have not given, and do not intend to give, the slightest thought to critiquing management or Business practices and costs. I can't see the point because there are far too many "unknowns" and it is clearly a very complex business.
The only things that have bothered me are to do with the operation and features of the Premium Membership scheme, especially data security.
