The only issue I've had in terms of health and safety has been tiredness whilst driving. I'm working late on the Tues/Weds evenings to try to make the time back, then early into the office, work most or all of the day then drive 200+ miles. I'm completely drained by the time I get back home.
I'm driving the distances, not using the train, because otherwise I feel trapped in the hotel, and have to get taxis to and from the office which would be frowned upon anyway (fuel card is centrally funded, taxis would be funded by the account).
Basically my days are:
Monday: WFH, or on occasion central London or Manchester
Tuesday: up early, drive 204 miles, work until COP then go to the hotel and work another 6 hours
Weds: up early, into the office, work until COP then go to the hotel and work another 6 hours
Thurs: up early, into the office, work as workload dictates (sometimes I'm lucky and can get away mid afternoon but sometimes it's 5-6pm) and then drive back. Depending on the flow of traffic this is often a 6-7 hour journey
Fri: WFH or local office
It means my wife, who works full time, is put under huge strain because I'm away so much and even when I'm here I'm completely drained. This is not what I signed up for. I'm having the right conversations in the right places but things are not moving as quickly as I would like so I'm looking at other roles already, internal and external.
