AIBU To think that DH needs to step up and be more proactive in motivating our DC? We both work full time so teenage children are pretty much left to their own devices during the week. They are thankfully pretty good about getting the school work done but when they're not doing lessons/homework they are glued to a screen and no amount of persuasion will get them out of the front door unless we are there to physically take them out which isn't possible when we're working.
I work on a Saturday & have just phoned home and they are all still in pyjamas watching TV
This isn't a one-off as pretty much every Saturday is 'laze around with dad while mum isn't there to nag us' day. They will do a bit of housework but frankly I'd rather they left the house work if it meant they actually went outdoors & got a bit of sunshine and let off steam. The kids don't mind and seem to be coping okay with lockdown but I don't think this is good for them in the long term plus really don't like the fact that the only time they get out is a walk on Sunday and same on my day off Tuesday when i take them out for a half hour run or walk. DH is the problem and I'm getting pissed off but just get told to stop nagging 
So, AIBU and given he does a physical job should I just leave them be or do we need a more serious conversation about parental responsibility?
