Nico Rosberg has competed for Mercedes ever since the German manufacturer returned to the Formula One grid at the beginning of 2010.
But loyalty, as he may find out in the coming months, counts for very little in this sport.
Rosberg has played an instrumental role in Mercedes' rise to prominence in recent seasons, yet team boss Toto Wolff has challenged the German to earn a new contract by proving he can work alongside his team-mate, three-time world champion Lewis Hamilton, in 2016 and beyond.
Rosberg, then, will be under a great deal of scrutiny in the first half of next season, and he may want to seek the advice of Marcus Ericsson, who knows all about driving under pressure.
After an unconvincing debut season in 2014, the Swede was beaten by his rookie team-mate Felipe Nasr in 2015, and Ericsson has revealed that his desperation to impress Sauber resulted in his inconsistent performances.
Meanwhile, Bernie Ecclestone believes Mercedes' current dominant streak may soon come back to haunt them, suggesting he is unsure how the Silver Arrows will react when the victories dry up.
All good things must come to an end, though, and after being dumped by Toro Rosso after three seasons at the end of 2014, Jean-Eric Vergne missed out on a chance to rejoin the grid with the brand-new Haas team in 2016.
The Frenchman, currently competing in the all-electric Formula E series, respects the American outfit's decision and has insisted his F1 career may not be over yet.
Also fighting for her F1 future is Carmen Jorda, who has spoken of her chances of remaining with Renault next season.After an unconvincing debut season in 2014, the Swede was beaten by his rookie team-mate Felipe Nasr in 2015, and Ericsson has revealed that his desperation to impress Sauber resulted in his inconsistent performances.
