I'm about to start mat leave and want to go down to 4 days a week when I go back, however, I'm not sure which day would work best. There will be a trial period to see if it would work for my company, but I'd like some insights. Friday for example is a bad day because it's delivery day (I work for a consulting firm), Wednesday's could work well because I'd start the week off with the team and be able to leave them to get on with it on Wednesday and then pick it up again until the end of the week. Monday because bank holiday usually falls on this day (these days a pro-rated).
