OP I do sympathise. My husband has either worked hybrid like you or worked from home with some travel to clients.
And the worst one was when he worked for a company in London which was supposed to be 3 days in London & 2 days at home. With travel to and from train station, travel there and back on train & tube he was looking at 3.5-4 hours travel every day he went in. As he got promoted he also ended up working later & working more when he got home.
Also because he wasnt there full time he couldnt get a season ticket & travel was very expensive.
It was really exhausting for him & left little time for family. He did it for about 6 years then found something else where he was working from home 5 days with some client travel. It was much better, he stopped being exhausted all the time, less stressed, and had time with the family. Plus he didnt have the travel costs.
So I would seriously advise you to change jobs.
Lastly, did you say something re salary? My husband tends to be very loyal and stay with companies he goes to for years at a time. The company he moved to from the London job he was there for quite a few years. Over time people get frustrated with companies and their companies can get lax with salary increments & rewards, training and taking the employee for granted. This happened with my husband, and when he finally got fed up enough to look elsewhere, he ended up getting a job with a very significant increased salary, training etc etc. When he other company heard he wanted to leave they panicked and offered an increase ofa quarter of what they had being paying. They knew they had underpayed him for years. He didnt take them up on it as he was fed up & went to the new firm.
So I would suggest it could be in your interests to look elsewhere from a salary point of view also. But the commute thing - definitely would be the nail in the coffin.
